A suspension device for suspending a sign or another article from an elongated object, which suspension device (1) comprises:—a base part (4);—a holder (3) connected to the base part;—two gripping shanks (10, 20) which are pivotally mounted to the base part and pivotable in relation to each other to and fro between an open position and a closed position, one of the gripping shanks being pivotable in relation to the base part about a first axis of pivotation and the other gripping shank being pivotable in relation to the base part about a second axis of pivotation, which extends in parallel with and at a distance from the first axis of pivotation;—at least one spring member (5a) acting between the gripping shanks; and—at least one gear mechanism (6a) with a first gear member (15a) rigidly connected to one of the gripping shanks and a second gear member (25a) rigidly connected to the other gripping shank, these gear members being in engagement with each other and arranged to be turned in relation to each other when the gripping shanks are pivoted in relation to each other. |

1. A suspension device for suspending a sign or another article from an elongated object, which suspension device (1) comprises:
a base part (4); a holder (3), which is connected to the base part (4) and to which an article is attachable; a first gripping shape (10) and a second gripping shank (20), which are pivotally mounted to the base part (4) and pivotable in relation to each other to and fro between an open position, in which the gripping shanks (10, 20) are pivoted away from each other to allow an elongated object to be inserted between the gripping shanks, and a closed position, in which the gripping shanks (10, 20) are pivoted towards each other to allow the n in shanks, to grip an object received between the gripping shanks and thereby clamp the suspension device (1) to the object; and at least one spring member (5a) acting between the gripping shanks, against the action of which the gripping shanks (10, 20) are pivotable from the closed position towards the open position, wherein the first gripping shank (10) is pivotable in relation to the base part (4) about a first pivotal axis (S1); the second gripping shank (20) is pivotable in relation to the base part (4) about a second pivotal axis (S2), which extends in parallel with and at a distance from the first pivotal axis (S1); the suspension device (1) comprises at least one gear mechanism (6a), which comprises a first gear member (15a) rigidly connected to the first gripping shank (10) and a second gear member (25a) rigidly connected to the second gripping shank (20), said first and second gear members (15a, 25a) being in engagement with each other and arranged to be turned in relation to each other when the gripping shanks (10, 20) are pivoted in relation to each other; said gear mechanism (6a) constitutes a first gear mechanism of the suspension device (1): the suspension device (1) also comprises a second gear mechanism (6b), which comprises a first gear member (15b) rigidly connected to the first gripping shank (10) and a second gear member (25b) rigidly connected to the second gripping shank (20), said first and second gear members (15b, 25b) of the secons gear mechanism (6b)being in engagement with each other and arranged to be turned in relation to each other when the gripping shanks (10, 20) are pivoted in relation to each other; the first gear mechanism (6a) and second gear mechanism (6b) are arranged in parallel with each other on opposite sides of the base part (4); the suspension device (1) comprises two covering plates (7a, 7b) arranged opposite each other, the first gear mechanism (6a) being covered on its outwardly facing side by a first one (7a) of these covering plates (7a, 7b) and the second gear mechanism (6b) being covered on its outwardly facing side by the other covering plate (7b); and these two covering plates (7a, 7b) are connected to each other through two pins (17, 27) extending between the covering plates and through the base part (4), the first gripping shank (10) being pivotally mounted on a first one (17) of these pins and the second gripping shank (20) being pivotally mounted on the other pin (27). |
